Listen To Local Radio On Windows Phone 7

I have seen several mobile apps that stream radio stations, but most of those only include select radio stations from select markets. Today I found TuneIn Radio for Windows Phone 7, and what immediately caught my attention are the number of radio stations in my market of Detroit, Michigan. TuneIn Radio has the majority of local radio stations in the Detroit Market, including my favorite stations, and it also includes lists some EMS, Fire Department, and Police Department dispatch streams, but so far I have not been able to have any of those play.
